Ultra-low Flow Controllers & Meters

Sierra Instruments new Micro-Trak is specifically designed for gas flow ranges under 4 sccm (smlm) with a minimum controllable mass flow rate of 0.1 sccm (smlm). Micro-Trak? is a specialized instrument for those who need accurate and reliable micro mass flow control of clean gases including corrosives and toxics. Excellent accuracy (+/- 1.0% of full scale) and reliability (+/- 0.2%) coupled with unsurpassed instrument stability offer customers an instrument they can depend on, month after month, year after year.


Sierra's Micro-Trak 101 Series - High Performance Digital Mass Flow Meters and Controllers for Ultra Low Gas Flows

As today's science and engineering focus more and more on micro technology, the requirement to be able to measure and control extremely low gas mass flows has become very important. With state-of-the-art sensor technology and highly engineered direct acting valve design, Sierra's Micro-Trak? accurately measures and controls micro mass flows of gas previously thought by scientists to be too low for a repeatable reading.
